How to validate email in mongoose

Question

Im new to Mongoose...I have a code snippet below. If I want to check what comes after the @ symbol in an email before I save, how would I do that validation?

var user = new User ({
     firstName: String,
     lastName: String,
     email: String,
     regDate: [Date]
});

user.save(function (err) {
  if (err) return handleError(err);
})

You can use a regex. Take a look at this question: Validate email address in JS?

You can try this

user.path('email').validate(function (email) {
   var emailRegex = /^([\w-\.]+@([\w-]+\.)+[\w-]{2,4})?$/;
   return emailRegex.test(email.text); // Assuming email has a text attribute
}, 'The e-mail field cannot be empty.')
